To all whom it may concern:

Be it known that I, FREDERICK V. WILD, Jr., of the city of Baltimore, int e State of Maryland, have invented cert n Improvements inBoxing-Machines to b Used in Connection with Can-Labeling Ma ines, ofwhich the following is a specification.

In the description of the said invention which follows reference is madeto the accompanying drawings, forming a part hereof, and in which-Figure 1 is a side elevation of the improved machine. Fig. 2 is a sideelevation the reverse of Fig. 1. Fig. 3 is an end view of Fig. 1 lookingin the direction `indicated by the full arrow in that iigure. Fig. 4 isan end View of certain parts of the machine looking in the directionindicated by the dotted' ar` row in Fig. 1. Fig. 5 is an enlarged detailof the machine. Fig. 6 is a top view of vcertain parts of the machine,together with cer-tain parts of a labeling-machine to which the presentinvention is to be applied. Fig. 7 is adetail of the machine.

Referring now to the drawings, 1 is the frame of the machine, a vportion2 of which constitutes the runway abutting the runway of thelabeling-machine (not shown) to which the present invention is applied.YThe `frame is shown in an inclined-position, as seen from either sidethereof.

By reference to Figs. 1 and 3 it will be seen that the runway 2leads'toan opening 3,'

which is bounded on three sides by the coaniing 6, which constitutes apart of the frame 1.

6 is a shaft adapted to turn easily in the stands 7, erected on thelupper part of the frame 1. This shaft carries the starwheels '9 and theroller 10, whichis situated between mechanism hereinafter described.

12 is an inclined movable platform guided by the rods 13, the platformhaving sleeves 14, which loosely iit the said rods.

The platform -12 is held yieldingly in itsA highest position by means ofthe flexible, straps 15, which connect the sleeves 14 with spring-.helddrums 16 (shown only in Fig.

land which rotate in cases 17. The'tension of the said springs is suchas to retain the platform in an elevated position except when the sameis occupied by four cans. Consequently when four cans are deposited onthe platform, as hereinafter described, it has a tend ency to descendand carry with it the cans Vresting thereon. -The platform, however,'is

supported while thefour causare being arranged thereon by means oftheupper sliding v bolt 19,shown best in Fig. 3,'and hereinafter more fullydescribed. y

On the platformV 12 are secured the partition-bars 20, which divide theplatform into four spaces for the reception of the cans.

These bars, when the platform is in its lowest position, register withsimilar bars 22,

which are on and project laterally from the bottom 23 of the frame 1. f

The partition-bars 22 are elevated somewhat above the bottom 23 of theframe 1 in order that a packing-box 24, in which the cans are to beplaced and shown onlyin dotted lines in Fig. 3, may be slid on rails 25up to the frame to receive them.

' The bolts 19, hereinbefore alluded to, 'are arrangedfto slide` in.bearings 26 on one side of the frame 1, and they are each connected byabell-crank 29to a vertical rod 30, adapted to slidein bearings 3l2` Theupper end of this rod is held yieldin'gly in contact with a cam 33,which is tight o n the shaft 6, by means of the coiled spring 34,confined endwise between a collar 35, to which the lower bell-crank 29is pivoted, and the=lower bearing 31.

The cam 33 has an operativespur 36, which the lug is caught by the lowerbolt, which as the platform descends is thrown inward.

39 is a shaft which rotates in bearings 40, carrying the tight beveledgear-Wheel 41'and the loose sprocket-wheel 42, the outer side of whichis provided with the clutch member or IOO face 43. The said shaft alsocarries a clutch member 44, slidingly splined thereto, having the groove45 to receive the end of the shifting bellecrank lever46, hereinafterdescribed.

The loose sprocket-wheel 42 is connected by a chain belt 47 (see Fig. 6)to a sprocketwheel 49, which is loose on the driving-shaft 50 of alabeling-machine (not shown) and which has a crank-handle 48 foroperating the said machine and discharging the labeled cans from it tothe boxing-machine.

The sprocket-wheel 49, which, as before stated, is loose on the shaft50, has a clutchface in like manner to the sprocket-wheel 42 on theshaft 39 of the boxing-machine. The shaft 50 of the labeling-machine isprovided with a clutch 53, slidingly splined to the said shaft,and thesaid clutch is ci rcumferentially grooved for the shifting bell-cranklever 54. The said clutch is held yieldingly in contact with theclutch-face of the sprocket-wheel 49 by means of the coiled spring 55,which extends between the bracket 56, to which the shiftingbell-crank'54 is pivoted, and the face of the clutch member 53.

The free arm of the bell-crank 54is connected by a wire 58 to an arm 59,pivoted at 60 to a guide 61, hereinafter described as forming a part ofthe frame 1. This arm has a toe 57, which is situated under a horizontalpart of the shifting bell-crank lever 46, below the pivot thereof.

The clutch faces or members of the sprocketwheels 42 and 49 are onopposite sides of the said wheels. Consequently when one sprocket-wheelis in clutch the other is out.

62 is a beveled pinion tight on the countershaft 64, supported inbearings 65, which is in mesh with the beveled gear-wheel 4l, and 66 isa tight spur-pinion on the lower end of the said counter-shaft.

67 is a rack, the teeth of which are in gear with the spur-pinion 66,fitted to slide in the guide 6l, hereinbefore alluded to, and 69 is theboxing-head or can-ejecting device secured to the inner end of the rack67 to push stacked cans into the box 24, as hereinafter described. Itsoutward movement or that toward the packing-box is produced through theagency of the spunpinion 66, and its inward or return movement iseffected by a coiled spring 70 on the shaft 64, having one of its endsattached to the bracket 7l and the other to the upper face of the saidpinion. As the head is forced outward the coiled spring 70is tightened,and the resilient act-ion of the said spring effects the withdrawal ofthe can-ejector or boxing-head or its inward movement.

73 is a spring-held bolt (sce Fig. 7) adapted to slide in a sleeve 74and engage with a lip formed on the end of the central one of the bars2O of the platform 12, and thus hold down that device while theboxing-head 69 is being pushed toward the box 24. The said springbolt isheld out of action by the can-ejecting device or boxing-head, as shownin Fig. 7,

77 is a lever pivoted to the lower arm of the Vbell-crank clutch-shifter46, the upper arm of which is adapted to engage with the pin 79,projecting laterally from the rack 67, as that device reaches its inwardlimit.

80 is a lever hinged to the lower end of the bell-crank clutch-shifter46. It is provided with a projection 81, which in one position of thesaid lever engages with a pin 82 in the lower end of a bell-crank S3,pivoted at 84 to the bottom 23 of the frame 1.

The upper arm of the bell-crank 83 has a pin S5, which passes looselythrough a hole in the bottom of the frame l. The upper arm of the lever8O is fitted to engage with the lower arm of the lever 77. A stop 88limits the motion of the lever 77. The spiral spring S6 serves to inducethe lower arm of the bellcrank clutch-shifter 46 to move toward theframe l and hold the sprocket-wheel 42 out of clutch. Another spiralspring (shown to the right of Fig. 4) is employed to project the pinthrough the frame l to its fullest extent.

S9 is a lever hinged to the bracket 90, carrying at one end a pin 91,which, like the one 85, passes loosely through a hole in the bottom ofthe frame l and at the other asuitable rod 92,which in certaincircumstances extends upward through the runway 2 into the path of thecans as they enter the machine.

The rod 92 is normally depressed, so as not to interfere with theentrance of cans to the machine; but when the platform 12 presses downthe pin 91 the said rod is elevated and acts as a stop to the cans, asbefore described.

On the shaft 6 is a collar 94,.(see Fig. 3,) having four equidistantdepressions in its surface, and 95 is a spring-held bolt which entersthe depressions in the said collar to cause the star-wheels J tohesitate at each quarter-rotation which represents the passage of onecan to the platform 12 and, fur ther, prevents momentum from carryingthe said wheels too far or past the position which they should occupywhen a can has passed one of their points.

Supposing the packing-box 24 to be in the position shownin Fig. 3 byitsdotted delineation, the various parts or elements of the boxing-machineto occupy the relative positions shown in the drawings, and the machineto be in operation, motion being communicated to the machine by means ofthe crank-handle of the driving-shaft of the 1abeling-Inachine, theoperation of the boxingmachine is as follows: The first can to pass thestar-wheels falls to the platform 12 and is prevented from rollingalo`ng the same by the first one of the partition-bars 20. The secondcan, which enters the machine at the next quarter-rotation of the star-Wheels, drops to and rolls over the first can, falls to the platform,and is stopped from rolling as was the first. The third and fourth cansfol- TOO IIO

lowthe same course as that of the preceding ones and are seated side byside onthe platform, as shown in Figs. 1 and 2. The upper bolt 19 havingbeen withdrawn from under the hinged lug 37 by the action of theprojection 36 of the cam 33, as described, the combined weight of thefour cans causes the platform to descend until thesaid hinged lug comesin contact with the lower bolt l9,which has just been pushed inward bythe resilient action of the spring 34, the projection 36 of the cam 33having passed the upper end of the vertical rod 30, and the platformcomes to rest. Four additional cans are now deposited on the platform oron thosealready seated on the platform, when that device again descendsuntil it reaches the bottom, and after the last four cans havebeenreceived the said platform strikes the pins 85 and 91 by reason of itsgravity.v The clutch member 44 is now pushed into gear with theclutch-face of the `sprocket-wheel 42, which is thusplaced in rotationand communicates its motion directly to the shaft 39, while the clutch`member 53, which slides on a feather onthe shaft 50 of thelabeling-machine, is detached from its sprocket-wheel, and the saiddriving-shaft coming to a stop further delivery of cans from thelabeling-machine is suspended.V The rod 92 beingthrown up in a mannerand bymeans before described serves as a stop to hold back the canswhichremain on the runway 2. Vlhenl the platform strikes the pin` 85, it (thepin) is forced down and changes the position of the bell-crank lever 83,and the lower arm thereof being swung to the left causes theoperation ofthe lever 80, which in turn actuates the lever 46 so as -to throw theclutch 44 into engagement with the clutch-face 43 of the sprocket-wheel42.

ThisV engagement effects the rrotation of' the e shaft 39, together withthe beveled gear-wheels 41 and 62, as alsoV the spurlpinion 66, and therack carrying the boxing-head is pushed to wardthe packing-box. At thesame time the sprocket-wheel 49 on the driving-shaft ofthelabeling-machine is thrown out of clutch by means of the wire 58 and itsattachments andL its projection 81 from the pin82, when the lowervarm ofthe bell-crank- 46 is drawn back by thespring 86 'and the sprocket-wheel42 unclutched while the one'49 is placed in clutch.

Theuncoiling of the spiral spring now causes the boxing-head to vbedrawn back .to its original position, andthe platform being releasedfrom engagementlwith the springbolt 7 3 ascends tol its highest andoriginal position,when the stackingof cans,as described,

is repeated. When the second stack of twelve complement of cans, and aboxing-head with,
